Background The purpose of this study was to evaluate the impact of the pretreatment Glasgow prognostic score on treatment-related toxicities, tolerance, and survival in patients with advanced head and neck cancers undergoing concurrent chemoradiotherapy (CRT). Methods We retrospectively analyzed and compared the clinical characteristics, toxicities, and survival of 143 patients with stages III, IVA, and IVB head and neck cancer treated with concurrent CRT according to their Glasgow prognostic score between 2007 and 2010. Results The Glasgow prognostic score was correlated with advanced tumor stage and T/N classification. Patients with a higher Glasgow prognostic score were less likely to tolerate concurrent CRT, experienced more weight loss, required tube feeding support more frequently, and had higher percentage of grade ≥3 hematological toxicities, sepsis, and toxic death. Patients with a Glasgow prognostic score of 0 had better overall and recurrence-free survival than those with a Glasgow prognostic score of 1 or 2. Conclusion Pretreatment Glasgow prognostic score predicts treatment tolerance, toxicity, and survival in patients with advanced head and neck cancer undergoing concurrent CRT.

Background The purpose of this study was to evaluate the impact of metformin on toxicities and survival in patients with head and neck cancer undergoing concurrent chemoradiotherapy (CRT). Methods We retrospectively analyzed and compared the clinical characteristics, treatment tolerance, toxicities, and survival of 252 patients with stages III, IVA, and IVB head and neck cancer undergoing concurrent CRT with and without metformin treatment between 2007 and 2010. Results Among all patients, 39 patients received metformin whereas 219 patients did not. Both groups had similar clinical characteristics and nearly identical disease-free survival and overall survival. However, the metformin group was less likely to tolerate cisplatin, experienced more weight loss, had a tendency to receive lower doses of radiotherapy, required more feeding tube support, and had grade ≥3 nausea/vomiting and hematological toxicities. Conclusion Patients with head and neck cancer undergoing concurrent CRT along with metformin treatment require more careful multidisciplinary assessment and supportive care to ensure successful completion of treatment and avoid treatment-related toxicities.

Objective This study aims to evaluate the impact and potential prognostic roles of the pre- and post-treatment Glasgow prognostic score (GPS) and the change thereof in patients with advanced head and neck cancer undergoing concurrent chemoradiotherapy (CCRT). Methods We collected GPS and clinicopathological data of 139 stage III, IVA, and IVB head and neck cancer patients who underwent CCRT between 2008 and 2011. Their GPSs pre- and post-CCRT and the change thereof were analyzed for correlations with recurrence and survival. Results The GPS changed in 72 (51.8%) patients, with worse scores observed post-CCRT in 65 (90.3%) of the GPS changed patients. Patients in the improved GPS group showed a tendency toward better survival. From the multivariate analysis, the post-CCRT GPS level was an independent prognostic factor in addition to tumor stage. Conclusions After CCRT, a high GPS was revealed to be an important predictor of survival for advanced head and neck cancer.

Paper-based clinical outcome data collection methods have practical limitations when used in clinical settings, as the data are often not summarized in time to facilitate patient–physician communications and therefore cannot be used in clinical decision making. This study aimed to develop a computerized clinical outcome assessment tool (COAT) and evaluate its acceptability, feasibility, and potential clinical applications during clinical encounters for patients with head and neck cancer (HNC). The traditional Chinese (TChi) character version of the Functional Assessment of Cancer Therapy-Head and Neck (FACT-H&N) questionnaire was first transcribed and implemented into a touch-screen computerized administration and reporting system (COAT-HNC for short). Each HNC patient was invited to complete the COAT-HNC during their scheduled clinic visits as part of their clinical care. Upon completion, a structured summary report was generated, and subsequently used for treatment evaluation and planning. A cohort of 385 HNC patients were enrolled. Each scale of the computerized TChi FACT-H&N questionnaire demonstrated acceptable internal consistency, with Cronbach coefficient alpha ranging from 0.74 to 0.90. The touch-screen-based and audio-capable COAT-HNC was reported to be easy to use. Patients and physicians were able to utilize the summary report during their clinical encounters to discuss treatment progress and to plan care. It is practically feasible to design, develop, and implement the COAT-HNC system in routine HNC care. The COAT-HNC has the potential to become a valuable tool for data collection and management of clinical outcomes, and appears useful for HNC patients. However, larger studies to demonstrate its clinical usefulness are still needed.

This study was designed to evaluate the impact of the prognostic nutritional index (PNI) on treatment-related toxicities and tolerance in patients with advanced head and neck cancers who were undergoing concurrent chemoradiotherapy (CCRT).We retrospectively analyzed and compared the clinical characteristic, toxicities and survival of 143 patients with stage III, IVA, and IVB head and neck cancer who were treated with CCRT according to their PNI between 2007 and 2010.Low PNI was correlated with T classification and advanced tumor stage. Patients with low PNI were less likely to tolerate CCRT, required tube feeding support more frequently and had higher percentages of grade 3/4 hematological toxicities, sepsis and toxic death.Pretreatment PNI predicts treatment-tolerance and toxicity in patients with advanced head and neck cancer undergoing CCRT.

Background In this study, we aimed to investigate the impact of surgical procedures on the body image of head and neck cancer patients treated with radiotherapy and with or without radical surgery. Methods A cross-sectional survey of 150 patients with head and neck cancer was conducted. Sixty patients had nasopharyngeal cancer treated with definitive radiotherapy without surgery, and 90 patients had oral cavity cancer treated with radical surgery plus adjuvant radiotherapy. All participants completed a 10-item Body Image Scale (BIS) questionnaire to assess body image dissatisfaction. Among all patients, the socio-demographic and clinical variables were age, gender, partnership, education, employment, and radical surgery. In surgically-treated patients, the clinical variables were facial skin sacrificed, mouth angle sacrificed, glossectomy, maxillectomy, and mandibulectomy. ANOVAs, t-tests, and multiple regressions were used to evaluate the relationships between these variables and BIS results. Results In all patients, radical surgery was the strongest independent predictor of BIS scores. Surgically-treated patients had significantly worse BIS scores than the patients without surgery. In surgically-treated patients, facial skin sacrificed, mouth angle sacrificed, maxillectomy, and mandibulectomy were significantly associated with body image. According to multivariable analyses, inferior maxillectomy and segmental mandibulectomy were independent prognosticators of a poor BIS score in surgically-treated patients. Conclusion Radical surgery for head and neck cancer patients has a significant impact on their body image, especially for those undergoing facial bone destructive surgery.

The purpose of this study is to compare the treatment outcome of different radiation doses of elective neck irradiation (ENI) in nasopharyngeal carcinoma (NPC) patients treated with intensity-modulated radiotherapy (IMRT). In total, 504 patients with nondisseminated NPC who underwent magnetic resonance imaging before radical IMRT between 2000 and 2008 were retrospectively reviewed. The patients were classified into 2 groups based on the ENI dose: low ENI when the ENI dose was 46 Gy (n = 446) and high ENI when the ENI doses were 50 to 60 Gy (n = 58). All the patients in both the groups received a median dose of 72 Gy to the gross tumor and involved nodes. The fraction size was 2 Gy per fraction. Matching was performed between low ENI and high ENI in a 2:1 ratio, and the matching criteria were N-stage, T-stage, treatment modality, pathology classification, sex, and age. The median follow-up for all patients was 63.5 months. In all patients, the 5-year progression-free survival (PFS), local control (LC), regional control (RC), distant metastasis-free survival (DMFS), overall survival (OS), and cancer-specific survival (CSS) for low ENI and high ENI patients were 69.0% and 63.2% (P = 0.331), 89.0% and 83.9% (P = 0.235), 90.1% and 85.2% (P = 0.246), 86.8% and 76.6% (P = 0.056), 77.5% and 80.8% (P = 0.926), and 84.4% and 82.5% (P = 0.237), respectively. In the matched-pair analysis, the 5-year PFS, LC, RC, DMFS, OS, and CSS for matched low ENI and high ENI patients were 74.1% and 63.2% (P = 0.134), 92.0% and 83.9% (P = 0.152), 90.1% and 85.2% (P = 0.356), 86.2% and 76.6% (P = 0.125), 87.0% and 80.8% (P = 0.102), and 88.6% and 82.5% (P = 0.080), respectively. In the multivariable analysis for all patients, the ENI group was not a significant factor for PFS, LC, RC, DMFS, OS, and CSS. A low ENI dose of 46 Gy in 23 fractions is feasible in NPC patients treated with IMRT, and this concept should be validated in the prospective studies.
